How to reproduce

I have a batch script that prints valid custom "profiles" that I created for my work. It took a lot of time to print the whole table. I can share with you an example.

`@echo off
setlocal
call colors.bat

ECHO.
printf "%IPurple%Valid Profiles are:%Full_Color_Reset%"
ECHO.
printf "-----------------------------------------------\n"
printf "|     Profile     |          Proyect          |\n"
printf "-----------------------------------------------\n"
printf "|LRD ------------> L. & R. Distributors, Inc  |\n"
printf "|etrain ---------> Dematic's Etrain           |\n"
printf "|ELI-LILLY-CON---> Elli Lilly Concord         |\n"
printf "|Eli-Lilly-RTP --> Elli Lilly RTP             |\n"
printf "|Eli-Lilly-IDAP -> Elli Lilly Indianapolis    |\n"
printf "|ACE ------------> ACE Hardware               |\n"
printf "|GRI ------------> Groupe Robert Inc.         |\n"
printf "|loblaw ---------> Loblaw.                    |\n"
printf "|AMC ------------> Americold.                 |\n"
printf "|CE -------------> Cooper Electric.           |\n"
printf "|CEMD -----------> Capital Electric MD.       |\n"
printf "|NC -------------> North Coast.               |\n"
printf "|HH -------------> Home Hardware.             |\n"
printf "-----------------------------------------------\n"
ECHO.
printf "%IYellow%example:%Full_Color_Reset%"
ECHO.
rem // Store current code page in a variable for later restore (optional):
for /F "tokens=2 delims=:" %%C in ('chcp') do set /A "$CP=%%C"
rem // Change code page to UTF-8 Unicode:
chcp 65001 > nul
printf "%IWhite%λ%Full_Color_Reset% switchCmderProfile GRI"
rem // Restore original code page (optional):
chcp %$CP% > nul
ECHO.

endlocal`

Whats wrong with echo?

This is not a Cmder bug.

@jnambo printf is some kind of external program.

The issue is either with printf or maybe with ConEmu, but the issue is not related to Cmder.

Most likely one of the following has happened, and these are things you could investigate:

  1. Maybe there's been a change in the printf program.
  2. Maybe an antivirus system is taking longer than usual to analyze whether printf is safe to run.
